Born with distinctive white skin in a prehistoric setting, the infant was immediately rejected and abandoned by his tribe. Left to perish, he was rescued and adopted by a female ape named Kitty, who raised him as her own. Under her care, he developed survival skills and grew into adolescence within the natural environment.

Kitty's violent death during an attack by the predatory dinosaur Tirano (also referred to as Tyranno) became a pivotal event, catalyzing his departure. This tragedy ignited a dual purpose: to avenge Kitty's death by confronting Tirano and to seek out his biological human mother, whose existence he learned of after her demise.

His solitary journey led him to cross paths with the siblings Ran and Don, who became his steadfast companions, marking a significant shift from isolation. Through shared adversities, including tribal conflicts and natural threats, he demonstrated loyalty and protective instincts, notably training Don in archery to enhance the siblings' safety.

His quest involved navigating diverse challenges across varied landscapes. Encounters with other survivors of Tirano's attacks, such as the warrior Kiba—who bore a personal vendetta against the dinosaur—further shaped his understanding of loss and resilience. These interactions surfaced internal conflicts, including moments of emotional detachment or harshness, as observed when he displayed indifference toward a dying elder.

The search for his biological mother intertwined with broader themes of belonging and identity. An episode involving a tribal chieftain's corrupted power and the imprisonment of the chieftain's son prompted reflections on maternal bonds, revealing his persistent yearning to comprehend his origins.

His evolution transitioned from an outcast reliant on animal guardianship to an independent figure capable of forging human alliances, confronting physical and emotional trials, and pursuing justice amidst a perilous prehistoric world.
